Mac use better parts then PC's and i did a custom upgrade and got better parts put in. Reliablity and the operating system alone are worth spending the extra bit. I work with with computers and am over the amout of repairs and other crap i deal with on a daily basis. In the 5 years i have worked with computers, i would of returned about 8-10 Macs in total in comparison to about 2-3 PC's weekly.
